Labeling Experience

Data Annotation Specialist

LabelboxSegmentation

As a Data Annotation Specialist, I performed high-volume annotation of geospatial, satellite, and potentially LIDAR imagery to support AI model development. I collaborated with machine learning engineers to develop and refine annotation protocols for consistency and reduced ambiguity. My work demanded strict adherence to high-quality standards and production quotas. • Annotated images for autonomous vehicle datasets using 3D cuboids and semantic segmentation. • Consistently maintained 98%+ accuracy across labeling projects. • Leveraged CVAT, VGG Image Annotator (VIA), Labelbox, and Scale AI for annotation. • Improved labeling guidelines, resulting in a 20% reduction in ambiguity.

AI Training Associate

TextClassification

As an AI Training Associate, I classified and labeled large volumes of text for chatbot intent and sentiment analysis. I flagged edge cases to help developers optimize model robustness and performed QA on peer-labeled data. My efforts drove improvements in model quality and annotation team consistency. • Labeled thousands of text datasets for chatbot intent categories and NER. • Conducted sentiment analysis on over 50,000 e-commerce customer reviews. • Used Amazon SageMaker Ground Truth, Labelbox, and CVAT for text and entity labeling workflows. • Supported quality assurance processes and bias reduction initiatives.
